Baller did not immediately respond to the Daily News' request for comment, but he wrote on Twitter that he wasn't "answering any questions about my boys engagement."

Neither Kardashian nor Chyna have commented on their reported engagement yet, but like Baller, Chyna's best friend — model Amber Rose — appeared to confirm it's legitimacy with a celebratory Instagram post on Tuesday.

"Congratulations to my Family @blacchyna and @robkardashian!!!" she wrote. "Pease (sic) don't let nothing or no one tear u guys apart! I never seen my sis so happy and I couldn't be more happy for her!"

Chyna sparked speculation that she and the ex-"Keeping Up with The Kardashians" cast member were engaged when she shared an Instagram photo of the dazzling ring early Tuesday morning with the caption "YES !...!...!"

Several members of the Kardashian clan have appeared to soften their stances in recent weeks, however, with his mother Kris Jenner admitting Chyna "seems like a really nice girl" in a recent radio interview.

Last week, Chyna strongly pined for the once-reclusive TV star to pop the question, reveling over the idea of starting a family with him in a Snapchat video.

"Rob, I am not playing with you, I want my eggs cracked," she said in the clip. "That means I wanna have a baby. I want my name dropped. That means I wanna be married."

Later in the week, Kardashian met Chyna's parents for the first time, and a few days later TMZ reported that Chyna's mom already believes he's "the one" for her daughter.
